Umgangatho weewelds zamabala eziveliswe ngoomatshini bokuwelda bamabala aphakathi amaza ombane ngowona ubaluleke kakhulu kumashishini ahlukeneyo. Eli nqaku lijolise ekuxoxeni iindlela zokuhlola ezisetyenziselwa ukuvavanya umgangatho we-spot welds kunye nokuqinisekisa ukuthotyelwa kwemigangatho efunwayo kunye neenkcukacha.
- Uhlolo olubonakalayo: Uhlolo olubonakalayo yeyona ndlela ixhaphakileyo kunye neyokuqala yokuvavanya umgangatho we-weld weld:
- Khangela iziphene ezibonakalayo ezifana nokudityaniswa okungaphelelanga, ukuqhekeka, okanye ukungahambi kakuhle kwi-weld nugget.
- Vavanya inkangeleko ye weld, kuquka ubukhulu bayo, imilo, kunye nokufana.
- Uvavanyo olungangonakalisi (NDT): Iindlela ze-NDT zisetyenziselwa ukuvavanya umgangatho we-weld ngaphandle kokonakalisa i-weld ngokwayo:
- Uvavanyo lwe-Ultrasonic (UT): Isebenzisa amaza omsindo we-high-frequency ukuze ibone iziphene zangaphakathi okanye ukungaqhubeki ngaphakathi kwe-weld, njenge-voids okanye ukungabikho kokudibanisa.
- Uvavanyo lweRadiographic (RT): Kubandakanya ukusetyenziswa kwe-X-reyi okanye i-gamma ray ukubamba umfanekiso we-weld kunye nokuchonga naziphi na iziphene okanye ukungahambelani.
- Uvavanyo lweMagnetic Particle (MT): Ifumanisa iziphene ezikumphezulu okanye ezikufutshane nomphezulu ngokufaka amasuntswana omagnetic kwiweld kunye nokujonga indlela aziphethe ngayo phantsi kwemagnethi.
- I-Dye Penetrant Testing (PT): Ifaka ulwelo olunombala okanye idayi kwi-weld, engena kwi-surface-breaking defects kwaye ibonakala phantsi kokuhlolwa.
- Uvavanyo loomatshini: Iimvavanyo zoomatshini zenziwa ukuvavanya amandla kunye nentembeko ye-welds yendawo:
- Uvavanyo lwe-Tensile Shear: Ilinganisa amandla afunekayo ukutsala iisampulu ezidityanisiweyo, kuvavanywa amandla okucheba kweweld.
- Uvavanyo lwe-Peel: Uvavanya ukuxhathisa kwe-weld kumandla okuxobula, ngokukodwa okufanelekileyo kwi-lap joint welds.
- Uhlalutyo lwe-Cross-Sectional: Ibandakanya ukusika kunye nokuvavanya i-cross-section ye-weld ukuvavanya izinto ezifana nobukhulu be-nugget, indawo yokudibanisa, kunye nendawo echaphazelekayo ukushisa.
- Umlinganiselo wokuNchasa koMbane: Umlinganiselo wokuchasa umbane udla ngokusetyenziswa ukujonga umgangatho weewelds zamabala:
- Ukuchasana noQhagamshelwano: Ilinganisa ukuchasana kwi-weld joint ukuqinisekisa ukuhanjiswa kombane okufanelekileyo.
- I-Nugget Resistance: Imisela ukuchasana nge-weld nugget, engabonisa ukufaneleka kokudibanisa kunye nokunyaniseka.
Ukuhlola umgangatho we-spot welds kwi-medium frequency inverter spot welding machine kubalulekile ukuze kuqinisekiswe imfezeko yesakhiwo kunye nokusebenza. Ukuhlolwa okubonakalayo, uvavanyo olungonakalisi, ukuvavanywa koomatshini, kunye nokulinganisa ukuxhathisa kombane bubuchule obuxabisekileyo bokuvavanya umgangatho we-weld weld. Ngokusebenzisa ezi ndlela zokuhlola, abavelisi banokuchonga kwaye balungise naziphi na iziphene okanye ukungahambelani kwi-spot welds, ukuqinisekisa ukuthotyelwa kwemigangatho yoshishino kunye neenkcukacha. Ngokusetyenziswa kwemilinganiselo engqongqo yolawulo lomgangatho, iiwelds ezithembekileyo nezikumgangatho ophezulu zinokufikelelwa, zibe negalelo kwimfezeko iyonke kunye nobomi obude bezakhiwo ezidityanisiweyo kwizicelo ezahlukeneyo.
